Thankyou !!

The info was right on ! Thank You !, it was the crank sensor but removing broken piece in the block seems impossible. A guy says he has a tool for that . I don't. I tried leaving it in for a five mile gamble but the car stalled and the battery was dead just like that. Removed the new one thinking it was broke but it was'nt. Fished around with thin metal objects and I can get the piece to almost lift but it seems caught. Can I remove the oil pan and pluck it out ? Did I ruin the motor by leaving the other piece in there ? Please help , Thanks , Eric It's a 2.5 1986 Century Buick

I need help to find the location of the crank sensor for the 1986 century crank sensor. Also is there a coil sensor? And where is the brain located and can it be tested? Is there a site with pictures and instructions? Thanks Eric

Thank you

My friend has a 1987 Century. It originally came with a six cylinder and now has a 2.5 four cylinder. He just bought it used and has had troubles since. It first was overheating then after removing thermostat seemed better then it did'nt. We changed the radiator cap, washed the radiator fins , flushed the radiator an block to no avail. It was hard to determine because it was intermitant. Then it seemed it would start to overheat when he ran the ac. This has over 100k. Next it was not firing on cylinder no. 3. Now no fire at all. We have checked the coils Put on different ones, Put a new ignition module plate and still nothing. One guy said it has to be the coil sensor. Is this the item on the underside of the ign. module that protrudes into the motor? And if so this one looks like it might be broke off. Can anyone tell me whats going on. And is there a link between the overheating and this no fire. I have heard that the 2.5 is a very good motor and its the worst they made. Is there a site that shows pics and info to help? Thanks Eric
